摘 要: 镁/铝合金有助于实现材料轻量化,通过半固态成形技术可以进一步改善镁/铝合金室温及高温性能,进而极大拓宽其应用范围。流变成形无需制坯和对坯料进行二次加热,成为未来镁/铝合金半固态成形技术发展的主要趋势。流变成形中最关键的是半固态浆料的制备。将几种常用的镁/铝合金半固态流变浆料制备方法按照接触式和非接触式2种类别进行分类,综述各种制浆方法中非枝晶组织的形成机理,介绍近年来国内外学者关于这些方法取得的研究成果,并对其发展方向进行展望。
关 键 词: 有色金属及其合金;流变成形;综述;镁合金;铝合金;半固态浆料

Abstract: Magnesium and aluminum are very attractive for realizing lightweight in structural materials, and semisolid forming is a promising way to improve both room temperature and elevated temperature mechanical properties of these alloys. Rheo-forming has been the main tendency of semisolid forming as for its no need for preparing billets and reheating them. The key technique in rheo-forming is to obtain good semisolid slurry, which contains non-dendrite microstructure. In this paper, methods on preparing semisolid slurry of magnesium and aluminum alloys are divided into two categories, namely the contact and the non-contact. Mechanisms of obtaining the non-dendrite microstructure are clarified respectively, and some related research achievements in recent years are also introduced here.
Key words: non-ferrous metal and alloy; rheo-forming; review; magnesium alloy; aluminum alloy; semisolid slurry
